Stellantis N.V. and Zeta Energy Corp. have entered a joint development agreement to push the boundaries of battery cell technology for electric vehicles (EVs). The partnership focuses on lithium-sulfur (Li-S) batteries, aiming to deliver groundbreaking gravimetric energy density while maintaining a volumetric energy density on par with current lithium-ion solutions.
For consumers, this innovation could result in significantly lighter battery packs offering the same usable energy as lithium-ion counterparts, translating to extended driving range, enhanced vehicle handling, and improved performance. Li-S batteries also promise up to 50% faster charging speeds, making EVs more convenient for everyday use. Furthermore, these batteries are projected to cost less than half the price per kWh compared to existing lithium-ion technology, presenting a cost-effective alternative.
The environmental impact of Zeta Energy’s Li-S batteries is another highlight. Manufactured using waste materials, methane, and unrefined sulfur—a byproduct from industrial processes—these batteries eliminate the need for materials like cobalt, nickel, manganese, or graphite. This approach significantly reduces CO2 emissions and aligns with sustainable manufacturing practices. The technology is designed to integrate seamlessly into existing gigafactory infrastructures and utilize a domestic supply chain within Europe or North America.
The collaboration encompasses pre-production development and production planning, with the aim to power Stellantis EVs by 2030. This advancement underscores Li-S technology’s potential to outperform traditional lithium-ion batteries in performance and affordability, while reducing supply-chain risks and supporting sustainability goals. “Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” said Ned Curic, Stellantis Chief Engineering and Technology Officer. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”
“We are very excited to be working with Stellantis on this project,” said Tom Pilette, CEO of Zeta Energy. “The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs.”
